Hezhou esp32c3 coin-operated musical toy

Overview

## A rookie project, my first reflow soldering record.

I used extra bottles and plastic chips at home to make a coin-operated toy that plays music and flashes lights.

### Features of the project:
MP3 playback is completed based on Hezhou 9.9+ triode, without DAC and power amplifier modules. Suitable for toys, the sound size and timbre are good.

### Development tools
1. Software development: vscode + pio +arduino
2. 3D design: sharp3d

### Content
1. Project files
2. Source code
3. 3D source files
